(en) Derek Lowe, « The New Mutations », sur blogs.sciencemag.org, Science, (consulté le ) : « I should note here that there’s another strain in South Africa that is bringing on similar concerns. This one has eight mutations in the Spike protein, with three of them (K417N, E484K and N501Y) that may have some functional role. You’ll note the N501Y is also in the UK strain, but the E484K is one that people are particularly watching, because that’s in a region that a number of antibodies seem to recognize. ».
